superalloy

Supermalloy is Fe-Ni soft magnetic alloy actually.Supermalloy is easy to magnetize under the action of external magnetic field,and the magnetic induction strength is basically disappeared after the magnetic field is excluded.Besides,supermalloy has the very high magnetic permeability.Supermalloy can gather the lines of magnetic force good.So the soft magnetic alloy are widely used for the access of the magnetic field lines.
